Abstract
A field trial was conducted at Regional Research Station (coastal saline zone), BCKV, Akshaynagar, Kakdwip, South 24 Parganas (WB) during winter seasons of 2016-17 and 2017-18 to study the bio-efficacy of pinoxaden against the canary grass (Phalaris minor) and wild oat (Avena ludoviciana) in wheat and its effects on succeeding greengram crop. Application of pinoxaden at 352.9 g/ha recorded significantly greater reduction of targeted weed populations; however, it was statistically at par with its two lower doses of 156.86 and 176.47 g/ha. The higher dose of pinoxaden had greater weed control efficiency (WCE). Pinoxaden at 352.94 g/ha resulted in significantly higher grain yield compared to other treatments. Lower doses of pinoxaden at 156.9 and 176.5 g/ha were at par with hand weeding for grain yield. Therefore, the application of pinoxaden 352.94 g/ha at 30 days after sowing (DAS) can be a good option for canary grass and wild oat management in wheat - greengram sequence in coastal Bengal.
